Jark Wu reassigned FLINK-16609:
-------------------------------
Assignee: Shengkai Fang
> Promotes the column name representation of SQL-CLI
> --------------------------------------------------
>
> Key: FLINK-16609
> URL: https://issues.apache.org/jira/browse/FLINK-16609
> Project: Flink
> Issue Type: Improvement
> Components: Table SQL / Client
> Affects Versions: 1.10.0
> Reporter: Danny Chen
> Assignee: Shengkai Fang
> Priority: Major
> Fix For: 1.13.0
>
>
> The SQL-CLI now outputs the column name as the name that comes from the plan,
> which is not that readable sometimes, i can think of 2 cases that can be
> promoted:
> * Expression like "a + b" should output "a + b" (i.e. the MySQL CLI) instead
> of "$Expr{index}"
> * We should always output the alias if it's there, now, the alias in the plan
> may be dropped because of 2 reasons:
> 1. Project remove rule would remove the project without considering the
> alias
> 2. after CALCITE-3713, some CALC/PROJ would be reused while ignoring the
> column alias
